                      Glen Fernandes provided implementations of make_shared and
                      allocate_shared for arrays. They achieve a single allocation
                      for an array that can be initialized with constructor arguments
                      or initializer lists as well as overloads for default initialization
                      and no value initialization. See the '<a href="/libs/smart_ptr/make_shared_array.html">make_shared
                      and allocate_shared for arrays</a>' page for more information.

                      <code><span class="identifier">shared_ptr</span></code>
                      can now be used to hold a pointer to a dynamically allocated
                      array. This is accomplished by using an array type (<code><span class="identifier">T</span><span class="special">[]</span></code>
                      or <code><span class="identifier">T</span><span class="special">[</span><span class="identifier">N</span><span class="special">]</span></code>)
                      as the template parameter.

                      on C++11 compilers. This can break code that passes a smart
                      pointer to a function taking a <code><span class="keyword">bool</span></code>,
                      or that returns a smart pointer from a function with a <code><span class="keyword">bool</span></code> return type. Please use
                      <code><span class="identifier">p</span> <span class="special">!=</span>
                      <span class="number">0</span></code> or <code><span class="special">!!</span><span class="identifier">p</span></code> in such cases.
